Default energy imbalance

kabz is on a distinguished road
HI,

I'm solving energy equation (1d convection, 2d diffusion) with a solar energy source term. Residuals converge but when i apply energy balance it fails. I'm looking at the energy absorbed by computing, Q=mc_p(T_{out} - T_{in}, versus the energy available at the top BC, Q_{available}=\tao*G_{incident}) where \tao is the transmissivity of the glass.

Please help.
